I check the I2c device ( /dev/i2c-1 and i think is the correct one) also for the periferal register.
Is this abstraction working only with the Arduino expansio board?

I just start using my new intel Edison, I flash it to the latest firmware version, and install node-red. node version v0.10.38 node-red version 0.13.1
I'm trying to make the GlowingThermometer example with node-red (the original example is working correctly) starting from access the [BMP180(http://www.seeedstudio.com/wiki/Xadow_-_Barometer_BMP180) data. As soon I deploy the example of using the node-red-contrib-bmp085 abstraction the flow stops with this error.
